What the product description says
“Formulated with prebiotics, hyaluronic acid, peptides + squalane to plump skin with hydration”
Source: Tula

This product can help improve hydration of the skin with the two types of ingredients.

The first type is called “humectants”:
these ingredients help attract water. When humectants are on the surface of the skin, they “pull in” the moisture from the outside environment, or from within deeper layers of the skin. The following ingredients in this product do the job: glycerin, hydrolyzed hyaluronic acid.

This product also contains ingredients called “occlusives”. They help reduce the speed with which our skin loses moisture to the outside environment. These ingredients also help soften the upper layer of the skin, so it feels less tight and nicer to the touch. The following ingredients in this product do the job: caprylic/capric triglyceride, squalane.

SqualaneKey active· Emollient, OcclusiveEffect: HighAn oil naturally present in skin. Works as an emollient to soften the skin and form a protective layer on its surface without a greasy feeling.~0.5–0.75%
Hydrolyzed sodium hyaluronateKey activeEffect: HighAttracts water into the upper layer of the skin~0.6–0.95%
InulinKey activeEffect: HighHelps attract water to the upper layer of the skin. Is claimed to support the growth of "good" bacteria in skin (as a "prebiotic"), but the research is lacking~0.2–0.4%
LactobacillusKey activeEffect: HighA non-living ingredient made by fermentation with the bacteria Lactobacillus. It can help attract water to the upper layer of the skin and might help reduce inflammation~0.3–0.55%
Lactobacillus fermentKey active· HumectantEffect: HighA fermentation product created by bacteria Lactobacillus. The fermented product has anti-bacterial properties and might be helpful in calming down inflammation, but studies are lacking. Helps attract water to the upper layer of the skin. Can be used as a preservative~0.3–0.6%
Lactococcus ferment lysateKey activeEffect: HighConsists of remains of dead bacteria cells. Is likely helpful in attracting water to the upper layer of the skin. Might be helpful in reducing inflammation and neutralizing free radicals in skin~0.35–0.6%
Sodium acetylated hyaluronateKey active· HumectantEffect: HighA type of hyaluronic acid that works as an excellent moisturizer by attracting water into the upper layer of the skin. Is typically feels less sticky on the skin compared to the usual hyaluronic acid~0.5–0.8%
Sodium hyaluronateKey active· HumectantEffect: HighOne of the best moisturizing ingredients. Attracts water into the upper layer of the skin~1.3–1.6%
Sodium hyaluronate crosspolymerKey active· HumectantEffect: HighAttracts water into the upper layer of the skin~0.8–1.15%
Sodium lactateKey active· HumectantEffect: HighHelps attract water to the upper layer of the skin. Is often used to adjust the pH level of the product~0.2–0.35%
Sodium pcaKey active· HumectantEffect: HighNaturally present in skin and helps to attract water to its upper layer~0.2–0.4%
Alpha-glucan oligosaccharideKey activeEffect: HighHelps attract water to the upper layer of the skin~0.25–0.5%
Caprylic/capric triglycerideKey active· Emollient, OcclusiveEffect: HighA good mix of fatty acids that forms a protective layer on the skin. Improves the shelf life of products. Derived from coconut and glycerin~1.7–2%
GlycerinKey active· HumectantEffect: HighOne of the best moisturizing ingredients. Naturally present in skin. It attracts water to the upper layer of the skin working as a humectant~1.9–2.4%
Hydrolyzed hyaluronic acidKey active· HumectantEffect: HighOne of the best moisturizing ingredients. Attracts water into the upper layer of the skin. A version of it is naturally present in skin~1.1–1.3%

Polymnia sonchifolia root juiceEffect: LowA plant extract that helps attract water to the upper layer of the skin and might have some anti-oxidant properties~0.2–0.4%
Isononyl isononanoate· Emollient, OcclusiveEffect: LowForms a protective film on the surface of the skin to prevent moisture loss. Gives a velvety feel to products while reducing tackiness~3.2–3.9%
Caprylyl glycol· Humectant, EmollientEffect: LowHelps preserve products and creates a nice product texture~0.25–0.45%
Pentylene glycol· EmollientEffect: LowUsed to preserve products, dissolve other ingredients and create a nice product texture~0.25–0.45%

Lactic acidUnder-dosedEffect: HighAn exfoliating and moisturizing alpha-hydroxy acid (AHA). Typically causes less irritation than other AHAs, for example, glycolic acid. At high concentrations (about 15%), lactic acid can help reduce lines and wrinkles. Recent studies show that lactic acid can support the "good" bacteria living on skin's surface (healthy skin microbiome)~0.2–0.4%
Pyrus malus fruit extractUnder-dosedEffect: MediumCan have some moisturizing properties due to its sugar content~0.25–0.45%

Limited evidence
What the product description says
“improve the look of fine lines and wrinkles”
Source: Tula

This product does not contain ingredients that are able to reduce fine lines and wrinkles or help with skin elasticity, but it can improve the look of the skin temporarily through moisturization. Well-moisturized skin might also be able to repair the sun damage better.This ingredient - lactococcus ferment lysate - could be helpful for preventing or repairing signs of aging in theory, but there is no evidence that it actually works.

Lactococcus ferment lysateEffect: LowConsists of remains of dead bacteria cells. Is likely helpful in attracting water to the upper layer of the skin. Might be helpful in reducing inflammation and neutralizing free radicals in skin~0.35–0.6%
Lactic acidUnder-dosedEffect: MediumAn exfoliating and moisturizing alpha-hydroxy acid (AHA). Typically causes less irritation than other AHAs, for example, glycolic acid. At high concentrations (about 15%), lactic acid can help reduce lines and wrinkles.
